What fact is true regarding controllers and Aps in a split-MAC architecture?

• A.An IP tunnel is established between the AP and controller for AP management and control functions
• B.Using centralized data forwarding, frames leaving the Aps are never tagged Ethernet frames with VLAN identifiers
• C.Management and data frames must be processed locally by the AP, while control frames are sent to the controller
• D.With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator

You are troubleshooting a client issue on a Windows laptop. The laptop can see and connect to
2.4 GHz APs, but it does not even see 5 GHz APs. While evaluating the issue, you determine that this problem is happening for all of the laptops of this model in the organization. Several other tablets connect on channel 48 and channel 52 in the same work areas. What is the likely problem?

• A.The client drivers are faulty and should be upgraded
• B.The antennas in the laptops have insufficient gain to detect the 5 GHz signals
• C.The clients are configured to use WPA and 5 GHz channels only support WPA2
• D.The access points are configured to disallow 5 GHz

What advantages does using predictive site survey modeling software offer over performing a manual site survey? (Choose 2)

• A.It takes less time to create an initial site survey for a large facility when using predictive modeling software than when performing a manual survey.
• B.The exact impact of interference sources from external networks can be more accurately measured when using predictive modeling software than with manual surveys.
• C.Predictive modeling software makes it simple to assess multiple different AP locations and then adjust and display the AP's expected coverage pattern in almost real-time.
• D.Predictive modeling software can predict the ideal access point location 100% of the time, whereas the results from manual surveyingare less reliable.
• E.Predictive modeling software provides more reliable data than manual surveys when fine-tuning and validating access point placement after the installation.

802.11-2012?

• A.600-630 MHz
• B.5.15-5.25 GHz
• C.5.725-5.874 GHz
• D.2.4000-2.4835 MHz
